It was stated that nitrogen fertilization caused significant increase in aluminium phosphate fraction content and decrease in easily soluble phosphatase fractions. The phosphorus fertilization contributed to the increase of all determined forms of phosphorus, on the other hand potassium fertilizing did not influence in a statistically proved mode the concentration of the examined P forms. The phosphorus uptake by the vegetative parts was significantly and positively dependent on the amount of aluminium phosphate fraction amount in soil and iron phosphate fractions easily soluble by grain
